ok I thought I'd give the good word on my favorite new pedal.
I recently recived my EH Pocket metal muff. Its quite littraly pocket sized (well if you have fairly big pockets!), defenatly the smallest pedal on my board though (about half an inch smaller than a boss pedal in all measurements). This model has the least controls: only a volume knob distortion knob and a three possition mid scoop toggle switch (off/ slight scoop/full scoop). This thing has a LOT of gain, not the most I've ever heard but its still a lot, more than my Boss HM-2 by a long shot and defentaly more than a metal zone. The mid scoop switch is actually very well done and sounds 'right' (I have mine set on full scoop of course!). Its a bit of a one trick pony though you can get some reasonable mild distortions as well as the full on effect. Sticking an EQ pedal infront of it and boosting your mids into the pedal is a must if you have the scoop switch on full though.
no recordings at the moment but I can make some if people want to hear it
and the best thing about it is that it cost only £35 (from dolphin music) which is a really steal in my opinion.
